In fact, every single LGA775 CPU has NX except Gallatin P4 extreme, and I found some of s478 P4 has NX too, although you may not find it's NX feature in BIOS setup or in hardware detecting software, but those cpu can run Windows NX functions easily.

I have an old Celeron x86-only PC that can not run anything newer as Windows 7. But it still gets updates as it supports SSE2. Other machines without SSE2 stopped getting updates in 2018 (or '19?). Now on AntiX Linux.

Hey, guys, I'm wytiwx, I love CPU overclock and vintage hardwares, now I want to show you my works on running Win10 by Intel s478 CPU.

Before my thread, I must say thanks to @Jan1 and @FaiKee and many people, for your great research on Win8, that helped me a lot.

the only pic you are missing is the winver screenshot, wytiwx.
type winver.exe from the Run dialog box to show the Win10 version & edition and post that pic here.
need to know what specific win10 version you are running on your Intel s478 computer

I think the 1809 version of Win10 (that includes ltsc 2019) may have broken support for Intel s478 CPUs since that one did not work on old Intel "Yonah" based 32bit laptop cpus & certain Intel Pentium M "Dothan" cpus (these specific processors do have nx, sse2 & pae support but are 32bit only, no 64bit support)
the 1803 & older versions of Win10 (as well as the 1903 & higher versions) did work with these old x86/32bit laptop cpus - just not the 1809 version and would never boot up
